mongsn m'm h To all whom it may concern citizen of the United States, residing at West Rutland, in the county of Worcesterv and State of Massachusetts, haveinvented a: new and useful Loom-Shuttle, of whichthe following is a specifioation. Y

This invention relates to a loom shuttle, and more particularly to a detachable bobbin spindle for use in such shuttles. T hisatype of shuttle and spindle is largely used, in the weavingof worsted goods, and the yarn for such goods is often spun in outside or independent mills. The transportation and .increased handling of the bobbins thus incurred causes a large amount of breakage of the bobbins, particularly irr'the thintbarrel been cracked or broken it is difficult to weave off the yarn thereon without excessive yarn breakage when using the common type of spindle which has merely a small button or head to keep the bobbin in place. This worsted yarn is frequently very valuable and the waste of any portion thereof must.

be avoided.

It is the object of my invention to improve the construction of spindles of the type above described, rendering them more dura ble and eflicient in operation without sub stantially increasing the cost of manu'fac ture thereof.

With this object in View, one feature of my invention relates to the provision of a head for the bobbin spindle which is substantially larger in diameter than the barrel of the bobbin and in which also the yarnengaging surface is peculiarly adapted to increase the so-called throw of the yarn away from the tip of the bobbin."

Another feature of my invention relates to the provision of a spindle headof sufficient weight so that the spindle cannot be easily displaced upwardly by themovement of the h shuttle, and also of. sufficient strength to withstand injury if accidentally displaced.

A third feature of my invention relatesto the provision of an improved construction of spindle head by which the tip of the bobbin is more effectively centered and held in position. relate to certain arrangements and combinations of parts which will be hereinafter de Application filed-Septeniberj22, '116; j.Seria1..No.121,674, a a

Furthermore. the A yarn-engaging portion of the head is formed as a cylrnder of substantial length, which formation of thehead is found by experiment to substantially increase the throw? of the yarn away from the tip of the bobbin as it is wovenofi'. A typical broken bobbin i is shown inFig. 2, and the great utility of this feature of my invention by reference thereto.

The spindle head 20 is also provided with an elongated and gradually "tapered portion or extension. for engaging and 1 supporting the tip of-the bobbin. It is found that these bobbins vary somewhat in internal diameter and also that they weave ofl much better when firmly supported. By the use of the tapering extension of the spindle head each bobbinmay be firmly supported even .The' head 20 is formedof metal, preferably 7 7" though 7,

steel, and isof substantial weight.

Furthermore the shape and solid construction of the head 20 enables it to withstand injury even when it receivesa blow which would ruin the ordi- 7 Copies of this patent maybe obtained for nary type of spindle. If the head 20 is slightly dented or roughened by such engagement, the head contains sufficient material so; that the roughened parts may be easily smoothed off.

While I have particularly described the advantages obtained'by' the use of my improved spindle in connection with cracked or brokenbobbins, it is also of great utility with any bobbin in which the tip or barrel is in any way roughened or defective.

Having thus described my invention it will be evident that changes and modifications may be made therein by those skilled in the" art without departing from the spirit and scope of my invention as set forth in the claim, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is In a loom shuttle, a detachable bobbin spindle comprising a shaft and a solid metal head fixed to said shaft, said head having a tapered bobbin centering portion and a cylindrical end portion of substantially greater diameter than the bobbin with which it is designed for use and of substantial length whereby the throw of the yarn is increased, and being also of material weight relatively to said bobbin, whereby accidental upward displacement of the spindle and bobbin is prevented.

In testimony whereof I have hereunto affixed my signature.
